Fig. 2 shows the schematic layout of a part of the second embodiment of pultrusion apparatus according to the present invention.
Fig. 3 shows the schematic cross-sectional of the wind turbine including component according to the present invention.
Specific embodiment
Diagram in attached drawing is schematical.It should be noted that in different figures, element similar or identical is accorded with same reference Number.
Fig. 1 shows the first embodiment along longitudinal pultrusion direction X pultrusion apparatus 100 extended.Pultrusion at Type device 100 includes pultrusion die 20, and multiple fibers 110 are pulled through pultrusion die 20 to be immersed in resin In.
Pultrusion die 20 has rectangular cross section.
Pultrusion die 20 is conventional and in pultrusion technique field it is known that and therefore no longer by into one Step detailed description.
With reference to pultrusion direction X, in 20 downstream of pultrusion die, at least the pultrusion item 50 of transport portion forming.
Rove section 80 is set in 20 upstream of pultrusion die with reference to pultrusion direction X.In rove section 80, It collects multiple fibers 110 for example from multiple fiber bobbin (not shown)s and guides it towards pultrusion die 20.
Rove section 80 can be used in 20 upstream of pultrusion die (that is, entering pultrusion die 20 in fiber 110 Change the conduction property of Chosen Point 200 along multiple fibers 110 before).
Can be according to multiple standard selected elements 200, such as it is uniformly distributed along multiple fibers 110.
For this purpose, rove section 80 include one or more nozzle 82(in the embodiment in figure 1, two nozzles 82) with For the drop 60 of conductive adhesive to be injected or deposited at Chosen Point 200 along multiple fibers 110.Nozzle is mounted on multiple phases It answers on arm 83, arm 83 can be according to the mobile Chosen Point to reach multiple fibers 110 of direction Z transverse to pultrusion direction X 200。
According to other embodiments of the invention, arm 83 can move in the plane or on three-dimensional space.
Arm 83 can move above or below multiple fibers 110.
By injecting or depositing the drop 60 of conductive adhesive at Chosen Point 200 along multiple fibers 110, part changes Conduction property at pultrusion item 50.The drop 60 of conductive adhesive provides part connection between adjacent fiber 110, this, which is improved, draws The overall conductivity of extrusion 50.
Fig. 2 shows the second embodiment along longitudinal pultrusion direction X pultrusion apparatus 100 extended.According to Two embodiments are implemented to change along the multiple fiber 110 by changing size or the surface of fiber 110 in Chosen Point 200 Become the conduction property of Chosen Point 200.In particular, can by mill pressure (mash) or squeeze implement change fiber size or Surface.The mill pressure of fiber or the covering surface for squeezing chopped fibre 110, have the conduction property of difference.Removal destroys fiber 110 covering surface makes carbon core be exposed to outside, and therefore the electric conductivity of pultrusion item 50 is improved in part.
For this purpose, in this embodiment, rove section 80 includes around the rotation axis transverse to pultrusion direction X The wheel 85 and static plate 86 of Z rotation.Wheel 85 includes submitting around multiple radially protruding part 87(of rotation axis Z regular distribution Pitch four radially protruding parts 87 of configuration, the regular angular distance being 90 degrees to each other).Radially protruding part 87 is by flexible material system At, such as soft plastic material.Static plate 86 is provided with the uneven rigid surface 88 with multiple discontinuous portions.For example, Surface 88 can be made of sand surface.In rove section 80, fiber 110 passes through between wheel 85 and static plate 86.With one kind Mode selects the mutual distance between wheel 85 and static plate 86 to make, during the rotation that wheel 85 surrounds rotation axis Z, fiber 110 at the Chosen Point 200 periodically pinching between each of radially protruding part 87 and uneven rigid surface 88.Just The scrambling on property surface 88 causes the covering of fiber 110 to rupture, therefore carbon core is made to be exposed to outside.Radially protruding part 87 Flexible material prevents fiber 110 to be broken completely.Alternatively, radially protruding part 87 can be made of stiff materials, and take turns 85 It is provided with elastic supporting member for supporting optical member, pressure and friction between arm and static plate 86 can be limited, this, which has, prevents fiber 110 to be broken Identical purpose.
Fig. 3 shows the wind turbine 1 including component according to the present invention.Wind turbine 1 includes pylon 2, and pylon 2 is pacified On the base portion not being painted.Cabin 3 is arranged on the top of pylon 2.
Wind turbine 1 further includes wind rotor 5, with two, three or more blade 4(Fig. 1 perspective view In, only two blades 4 are visible).Wind rotor 5 can be rotated around rotation axis Y.Blade 4 radially prolongs relative to rotation axis Y It stretches.
Wind rotor 5 is rotatably coupled by means of rotatable shaft 9 with generator 30.
Other possible embodiments (being not shown in attached drawing) according to the present invention, wind rotor 5 and generator 30 directly revolve Turn ground connection (direct drive generator configuration).
The Bearing assembly 8 that is schematically painted is provided to be held in place rotor 5.9 edge of rotatable shaft Rotation axis Y extend.
